The console awaits its output handler, but both sample BMCs supplied a plain function, and both dropped the send_data coroutine. virshbmc additionally receives its stream callback on a libvirt thread, so the send goes through run_coroutine_threadsafe against the loop captured at activation, called asyncloop because the class already has a loop method it uses as a thread target. ServerConsole asked the session layer to retry, which a ServerSession cannot do: it never runs Session.__init__, so it has no timeout, and its _timedout does nothing. IpmiServer.logout was synchronous and an argument short while _cleanup awaits logout(False). The boot options handler answered, then read an unbound name and answered again with 0xff.

"""this is a quick sample of how to write something that acts like a bmc

to play:

run fakebmc

|
|
Chassis Power is off
|
|
# ipmitool -I lanplus -U admin -P password -H 127.0.0.1 power on
|
|
Chassis Power Control: Up/On
|
|
# ipmitool -I lanplus -U admin -P password -H 127.0.0.1 power status
|
|
Chassis Power is on
|
|
# ipmitool -I lanplus -U admin -P password -H 127.0.0.1 mc reset cold
|
|
Sent cold reset command to MC
